UPS. Apple will stay preparing to ship until it’s scanned in Louisville. Apple store still says PTS for mine but UPS has it in Incheon, if the UPS scan is correct, or on its way to Alaska.I pre-ordered for Friday 9/22 and it’s still preparing for shipping. I just found out I will be out of town for work starting 9/21 until 10/2. It says that once it ships, I can have it held at carrier for pickup but wondered if there is a time limit they will hold? Can’t remember if they send via UPS or FEDEX; it’s delivering to a Raleigh, NC address. Tried to ask on Apple chat suport but it is obviously AI and giving nonsensical responsesl.
